In practice, real-world physical workspaces and technological limitations restrict the free and unlimited exploration of an arbitrary large-scale virtual environment. This article provides an overview of the existing approaches and techniques for enlarging the walkable virtual space. The authors specifically focus on the methods that use spatial manipulation for spatial compression because it is one of the most promising, but underexplored methods for nonintrusive user redirection in a limited physical space.
